WINDOW-SASI-I-SECURING MEANS.

Application filed April 14, 1924. Serial N0. 706,368.

T all whom it may concern:

Be it known that 1, Isaac Earn, a citizen of the United States, residingin the borough of Manhattan,city, county, and State of New York, haveinvented certain new and useful Improvements in YVindow-Sash- SecuringMeans, of which the following is a specification sufiicient to enablethose skilled n the art to which the invention appertains to utilize thesame.

The object of my invention is the provision of means whereby the upperand lower sashes of windows may be effectually secured together invarious co-relative positions, so that either or both sashes may bepositively adjusted toa prescribed or desired extent or area of opening,and to this end the invention consists in the specific construction,combinationand arrangement of parts and appurtenances described andclaimed distinctive features bein the auto 7 23 matic action of the boltinthe locking and unlocking operations, and the use, inconjunctiontherewith, of a release key, all as hereinafter fully set forth' In theaccompanying drawings 1 illustrate apractical embodiment of the essen-..tial features of my. improvements in window sash securing means,although I do not limit myself to the identical form and construction ofparts shown by way of exempliiication, since modifications in minordetails andequiva'lent mechanical expedients may be resorted to withlike results and without departing from the spirit and intent of myinvention in this respect.

With this understanding:- Fig. 1, represents adjacent portions of upperand lower window sashes secured together by my locking device;

Fig. 2,'is a sectional elevation taken upon plane of line 2-2 Fig. 1;

Fig. 3, is a central vertical sectional elevation, upon an enlargedscale, of my improved sash securing mechanism, the parts being shown inlocked position;

Fig. 4-, is a transverse section taken upon plane of line 4+4: Fig. 8;

Fig. 5, is a view like unto Fig. 3, showing the operative parts inreleased position;

Fig. 6, is a face view of a mortise plate suitable for use inconjunction with my improved sash lock mechanism;

Fig. 7, is what may be designated as a top View, approximately actualsize of the bolt slide member of my sash securing means;

Fig. 8, is an elevation thereof taken at right angles to Fig. 7;

Fig. 9, is a central longitudinal section of the barrel or casing.

Fig. 10, is a front end elevation thereof;

Fig. '11, is an elevation of the inner side of the latch;

Fig. 12, is a sectional elevation taken upon plane of line 1212 Fig. 11;

Fig. 13, is an exterior elevation of my de vice when the operative partsare in the position shown in Fig.5; 7 7

Figs. let and 15, represent transverse sectional elevations taken uponplane of line 1%14, Fig. 8, illustrating the operative action of the keyin disengaging the latch from the inturned abutment of the casing.

M, is a mortise plate to be secured to the side of one of the sashes,preferably the upper one S, as indicated in Figs. 1 and 2 of thedrawings, my locking device being mounted on the other sash S, and thelocking device to the upper sash S, if preferred, the results attainablebeing essentially the same in either case. That is to say, the bolt 6*,maybe made to engage with any of the mortiseholes m, m, in said plate M,as may be found most expedient. I

C, is a cylindrical casing, contracted at its inner end to form thecentral bolt aperture 0, and formed at its outer extremity with theannular flange 0, having countersunk holes 0 c for the accommodation ofthe attach- 'ir .g screws 0 0 shown in Fig. l. The casing C, is alsoformed with an inturned abutment tongue or shoulder 0*, and with a 101.-gitudinal slot 0 for the accommodation of a screw stub b, which isprotuberant from the bolt slide B, whereby the latter is held againstrotative movement on its longitudinal axis while reciprocable withinprescribed limits within the casing C, as will beunderstood by acomparative reference more particularly to Figs. 3 and 5 of thedrawings. This screw stud I), also functions as a means of adjustmentbetween the bolt slide B, and the casing C, since it prevents thewithdrawal of saidslide B, from said casing C, while admitting of themanipulation of the slide.

The bolt 5*, is formed integral with the inner end of the slide B, whilethe forward extremity of said slide B, is formed with an lit) integral.spindle stud Z), on which is rotatably mounted the manipulative handleor knob K, formed with a hey slot L.

Pivotally mounted on one side of the spine portion of the bolt slide B,is a spring latch L, the spring Z, oi which tends constantly to holdsaid latch L, in engagement with the abutment o", oi the casing: C. A.coil spring is interposed between the inner end oi the easing C, and thebody oi. the bolt slide it, surrouinling the bolt. Zn, as shown more pantioularly in Figs. 53 and ot the drawings.

In operation. the parts being in-the position shown in Fig. 5, when thebolt slide is pressed ini': d by means ot the lcnoh K, and against theresistaure ot the coiled spring (1, the latch ll, automaticall springsinto engagement with the rear edge of the abutment 0*, as shown in Fig.:3, thereby holding the bolt 0, in engagement with a mortise W, of theplate M, as indicated in Fig. 52, ot the drawings.

WVhen the latch l is rtlensed from the abutment e" by means of a keyinserted through the slot in, of the manipulative knob It, the latterbeing; turned on the s 'iindle stud Z), to eiieet this result; thespring 11, returns the part automaticall to the position shown in F ,g.l, ot the drawings.

In Figs. 1 and 3 of the drawil'igs my securing;- means are shown asholding to sas shes S, S, in closed relationship, although it is obviousthat the sashes may i e held apart at various distances and elevations,by resort to the diilerent mortise holes m, in the plate M, and hencethat the area of window opening may be adjusted to requirements whileinsuring safety in that the sashes cannot be released except in aprescribed manner by means of a key inserted through the manipulativeknob K, oi? the bolt slide 13, as here inhett'ore set forth. Obviously,therefore, ventilation may be attained with safety,

since ingress and egress through the window thus protected will beprevented to an extent that would preclude accident from within orintrusion from without.

hat I claim as my invention and desire to secure by Letters Patent, is

1. il indow sash securing means 01": the character designated,comprising a casing formed with an inner abutment and with alongitudinal slot, a bolt slide mounted in said casing and torn'ied withan integral belt at one extremity, and an integral spindle stud at itsother extremity, a coil spring interposed between said bolt slide andthe inner end of the casino, a rotatable manipulative lUlOl) mounted onsaid spindle stud. and formed with a key slot, a screw stud on the boltslide exteiulingr throiurh said longitudinal slot in the casing, and aspring latch mounted on said bolt slide for engageinent. with saidabutment on the casing, substantially in. the manner and tor the puriiose set forth.

:2. ll indow oh securing means 01 the cbarzu-ter designated, comprisinga casing formed with an inner abutment and with a lougitiulinal slot, abolt slide mounted in said casing and tornied with an integral bolt atone extremity, and an integral spindle stud at its other extremity, acoil spring interposed between said bolt slide and the inner end of thecasing, a rotatable manipulative, hnob mounted on said spindle stud, andformed with a key slot, a serew stud on the bolt slide extending throughsaid longitudinal slot in the casing, and a spring latch li'xounted onsaid bolt slide for engagement with said abutment on the casing, and incombination therewith a mortise plate :iormed with a plurality oimortises for can 'agement with said bolt, substantially in the mannerand for the purpose set forth.

ISAAC BEIN.
